Achmad, is this a recent problem? I would start by checking ISA Protocol Rules and Site and Content Rules for SMTP Outbound. If this is okay, your problem might be DNS external resolution. Are you receiving email? If you're not check ISA Server Publishing Rules, you should have published your Exchange Server. -----Original Message----- From: Achmad Mursalin [mailto:ach_m@xxxxxxxxx] Sent: Jueves, 22 de Agosto de 2002 07:40 a.m. To: [ExchangeList] Subject: [exchangelist] queue smtp very long http://www.MSExchange.org/ Hai.
